Enum TypeKind 

pub enum TypeKind {
    Enum {
        labels: Vec<String>,
    },
    Composite {
        fields: Vec<(String, ColumnTypeName)>,
    },
}

v7.17.0 Phase 1.4 — flavour of the new type. Only ENUM is implemented; the variant set is open so Phase 1.5 (DOMAIN) and later (COMPOSITE, RANGE) can land without an AST shape migration.

v7.37.x (ζ-B Phase 1 composite accept) — added Composite for CREATE TYPE name AS (field_name field_type, …). Phase 1 stores the field list in the catalog so PG dumps that emit CREATE TYPE … AS (…) don’t error out; using a composite type as a column type lands in Phase 2 (Value::Composite encoding + ROW() literal + field-access syntax).

Variants

Enum

AS ENUM ('a', 'b', …). Order is preserved (PG enum labels are ordered).

Fields

labels: Vec<String>

Composite

AS (field_name field_type, …). Order matters; PG composite literals are positional.

Fields

fields: Vec<(String, ColumnTypeName)>

Trait Implementations

impl Clone for TypeKind

fn clone(&self) -> TypeKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TypeKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TypeKind

impl PartialEq for TypeKind

fn eq(&self, other: &TypeKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
